TUYA WIFI Door and Window sensor with alarm sound
The PST-MC400S is an advanced Tuya Smart WiFi Door & Window Sensor with a Built-in Alarm Siren and Vibration Detection. It functions as a direct-to-WiFi security contact sensor, but adds local deterrence via an integrated siren along with multi-sensor monitoring capabilities.
Key Features
- Double Alarm Deterrence: Simultaneously sounds a 90dB local siren to scare off intruders and sends real-time push alerts to your smartphone.
- Multisensor Detection: Monitors both open/close states (magnetic sensor) and physical vibration/tampering.
- Direct WiFi Connectivity: Connects straight to 2.4GHz WiFi networks; no separate Zigbee or smart home hub is required.
- Ecosystem Automation: Integrated into the Tuya Smart and Smart Life apps, allowing for advanced automations. Examples include turning on smart lights when opening a door at night or turning off the AC if a window is left open.
- Voice Control Integration: Works with Amazon Alexa and Google Assistant for status checking and smart home voice routines.
